Does it matter share host or cloud host?

Hi,

I want to purchase a host for my web application which is written in codeigniter.
I don't know should i purchase Share HOST or Cloud HOST. So far i was using Share Host and i don't have experience in cloud host.

What is important to me:
1- Loading Speed.
2- Compatible with CodeIgniter 3 to get the best result.
3- Ability of host panel. also easy to use

What i have on my web application:
1- online payment (paypal)
2- user control panel

Thanks for your advice
